Now, after manually adding a dozen of segments to a couple of multisegment downloads, each of whom was going at 634 KB/s, I managed to push total speed to about 840-960 KB/s. This is reliable proof that load balancing is working, but unfortunately not as good as previously when it was always at 1.2 MB/s even with just 2 segments or 2 files going on. 🙁
